/* Welcome to the source code for Android Programming Tutorials (http://commonsware.com/AndTutorials)! Specifically, this is for Version 3.2 and above of this book. For the source code for older versions of this book, please visit: https://github.com/commonsguy/cw-andtutorials All of the source code in this archive is licensed under the Apache 2.0 license except as noted. The names of the top-level directories roughly correspond to a shortened form of the chapter titles. Since chapter numbers change with every release, and since some samples are used by multiple chapters, I am loathe to put chapter numbers in the actual directory names. If you wish to use this code, bear in mind a few things: * The projects are set up to be built by Ant, not by Eclipse. If you wish to use the code with Eclipse, you will need to create a suitable Android Eclipse project and import the code and other assets. * You should delete build.xml from the project, then run android update project -p ... (where ... is the path to a project of interest) on those projects you wish to use, so the build files are updated for your Android SDK version. */ // //src\apt\tutorial\AlarmActivity.java package apt.tutorial;
